..Josh.: Hello, welcome to the Crutchfield online advisor group. My name is Josh. How can I help you today?
JJ: Can you tell me the differences between Klipsch HD 500 and 300? I saw one goes 4hz lower on the sub, and maybe 2" bigger.. is that it?
..Josh.: You do get deeper bass from the sub, and it has a has a dual-woofer center channel for better separation, and it uses aluminum-dome tweeters for brighter highs.
